Dynamics of large-amplitude geostrophic flows over bottom topography
large-amplitude geostrophic flows bottom topography
2009/11/13
We examine the interaction of near-surface and near- bottom flows over bottom topography. A set of asymptotic equations for geostrophic currents in a three-layer fluid is derived. The depths of the ac...
Longshore Currents, Upwelling and Bottom Topography
Longshore Currents Bottom Topography Upwelling
2009/3/26
The effect of shelf-like bottom topography on a steady, linear, stratified, three-dimensional model of coastal upwelling is examined. It is shown that the presence of the bottom slope 1) reduces the r...
Continental Shelf Waves and Alongshore Variations in Bottom Topography and Coastline
Continental Shelf Waves Bottom Topography Alongshore Variations Coastline
2009/3/7
The effects of alongshore variations in bottom topography and coastline on the wind-stress-forced barotropic motion over a continental shelf and slope are studied. Perturbation methods are used to obt...
The Effects of a Variable Coriolis Parameter, Coastline Curvature and Variable Bottom Topography on Continental Shelf Waves
Variable Coriolis Parameter Coastline Curvature Variable Bottom Topography Continental Shelf Waves
2009/3/7
The effects of a variable Coriolis parameter, coastline curvature and variable bottom topography on continental shelf waves are examined for the case when the variations occur on a length scale much g...
The Influence of Bottom Topography on Upwelling off Peru
Bottom Topography Upwelling off Peru
2009/2/18
The x-y-t, two-layer β-plane numerical model developed by Hurlburt (1974) is used to examine the upwelling system off Peru. The region off Peru from 14 to 15°30's is one of strong and persistent upwel...

Barotropic Continental Shelf Waves Irregular Bottom Topography
2009/2/16
Using a geometry which roughly approximates that of a typical continental shelf and slope, the effects of a random bottom topography on free barotropic shelf waves are found. The bathymetric irregular...
The Generation of Continental Shelf Waves by Alongshore Variations in Bottom Topography
Continental Shelf Waves Alongshore Variations Bottom Topography
2009/2/13
The effects of alongshore variations in bottom topography on wind-stress-forced barotropic motion over a continental shelf and slope are studied. An idealized channel model with a weakly sloping botto...
Satellite Observations of the Influence of Bottom Topography on the Seaward Deflection of the Gulf Stream off Charleston, South Carolina
Bottom Topography Seaward Deflection Gulf Stream
2009/2/13
High-resolution thermal infrared data from the NOAA polar orbiting satellites are studied for the Gulf Stream between Florida and Cape Hatteras from the fall of 1974 to the spring of 1977. The sea sur...
Quasi-Geostrophic Waves in a Stratified Ocean with Bottom Topography
upper layer component lower layer component Quasi-Geostrophic Waves
2009/2/9
Quasi-geostrophic waves in a two-layer ocean with bottom topography on a β-plane are examined in detail. The bottom slopes in an arbitrary direction but gently and uniformly. A clear understanding of ...
